Thanks.  We might use that if that's the best we can do, but I want
something that works at compile-time, so that cross-compilation works.

How about this program instead?  It should fail to compile with the
buggy AIX compiler, but it should compile successfully with non-buggy
compilers.

   #include <stdbool.h>
   char c[] = "0123456789";
   int x = 1 / (&(c + 5)[-2 + (bool) 1] == &c[4]);
   int main() { return !c || !x; }
